A worker is making wooden triangles to use as obstacles for mini golf. The triangles can have any of the lengths shown. A triangle can be isosceles, but none can be equilateral. Name the side lengths of four different triangles to be used as obstacles. No two triangles can have the same set of lengths.

please NO links.

factor trees are nice.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
